Update the openshift-tests orchestrator to respect test isolation requirements advertised by extension binaries via the resources.isolation field. The orchestrator must ensure that conflicting tests or configurations, identified by a common conflict name, are not run simultaneously. Implement the logic to handle the different isolation modes (instance, exec, bucket) to prevent conflicts during parallel test execution.

This allows us to have more advanced isolation – something in between "parallel with anything" and "only serially execute."
